Abstract: A drive arrangement of a conditioning apparatus of a forage harvester having two conditioning rollers, with at least one of the conditioning rollers able to be driven at variable speed via an electrical drive train, includes an electric motor/generator for driving the conditioning roller. The electric motor/generator is able to be operated as a generator for braking the conditioning roller and to return the generated electrical energy into a drive system of the forage harvester.

Abstract: A system for lubrication of a bearing of a crop transport and/or processing system of a harvesting machine includes a supply container for storing a lubricant, a delivery pump and a lubricant line for delivering the lubricant from the supply container to the bearing, and a drainage channel and a suction pump for returning the lubricant from the bearing to the supply container.

Abstract: An operating device is provided for a vehicle, in particular for an agricultural or industrial utility vehicle. The operating device comprises a manually actuatable control lever. The control lever is used to adjust or modify the speed of the vehicle. The control lever is adjustable in a longitudinal direction, in order to adjust the speed of the vehicle. An implement with which at least one working function may be performed may be fitted to the vehicle. In order to enable ergonomic operation, it is proposed that the control lever comprise at least one operating element, with which the implement may be driven, and that the operating element be arranged so as to be movable together with the control lever in the longitudinal direction.
